Survey of LATCH vehicle hardware

Ninety-eight 2010–2011 model year vehicles were surveyed to evaluate the usability of hardware known as Lower Anchors and Tethers for Children, or LATCH, required by US FMVSS 225. Most vehicles do not provide LATCH hardware beyond the minimum number of required seating positions. Only seven vehicles had three sets of LATCH hardware in the second row. In 21 vehicles with third rows, four had no tether anchors and 11 had no lower anchors in the third row. Relative to proposed the Society of Automotive Engineers (SAE) recommendations, 59 vehicles met the recommended lower attachment force of 75 N or less but only 2 vehicles met the recommended clearance angle of at least 75º. The depth of lower anchors relative to the bight was less than 2 cm in 28 vehicles, 2–4 cm in 34 vehicles and greater than 4 cm in 36 vehicles. Most tether anchors were on the seat back (42) or rear filler panel (35).
